ajax error in fragment

[Barry Levine]

Hi All,
I'm running OpenMRS 1.10 with ref app 2.1 and using jetty on iMac/Yosemite
When I make an ajax call from a fragment it seems the method is invoked correctly but there is an error when returning from the method. In the following fragment code snippet selectedValue is a Concept. Here's the code snippet of fragment ajax call, along with the method:

 
        jq.getJSON('${ ui.actionLink("getLabSetConceptsForConceptId") }',
           {
             'labsetttt': selectedValue
            })
       .error(function(xhr, status, err) {
            alert('AJAX error ' + err);
        })
        .success(function(ret) {
                                var table = document.getElementById("labTable");
...

        public List<SimpleObject> getLabSetConceptsForConceptId(
            @RequestParam(value = "labsetttt", required = false) Concept labSet,
            @SpringBean("conceptService") ConceptService service,
            UiUtils ui) {

        ArrayList<Concept> labSetMembers = new ArrayList<Concept>();
        System.out.println("**********getLabSetConceptsForConceptId: " + labSet.getDisplayString());

        for (ConceptSet labSetMemberConceptSetItem : labSet.getConceptSets()) {
            Concept member = labSetMemberConceptSetItem.getConcept();
            System.out.println("**********Concept set member:  " + member.getDisplayString());
            labSetMembers.add(member);
        }
         return SimpleObject.fromCollection(labSetMembers, ui);

IN THE METHOD CODE SNIPPET THE VALUES FOR labSet and labSetMembers ARE GOOD - THE ERROR OCCURS AFTER THE return - THE ERROR ALERT FROM THE FRAGMENT INDICATES "AJAX error Error invoking fragment action"


I'm running jetty from the terminal, which provides the following output (note, values for labSet/labSetMembers are fine) and error message:


**********getLabSetConceptsForConceptId: Eye diagnoses
**********Concept set member:  Trachoma
**********Concept set member:  Viral conjunctivitis
**********Concept set member:  Trichiasis of eyelid
**********Concept set member:  Disorder of eye
**********Concept set member:  Neonatal conjunctivitis

Hi Barry,

Are you able to run this under your IDE's debugger?

If you include the uiframework code in your workspace/project, then you should be able to use a breakpoint to debug what exactly is happening here, and why :

Caused by: java.lang.NullPointerException

Hi Darius,
Thanks for your reply...I found the issue - it was caused by not providing the properties argument in return SimpleObject.fromCollection(labSetMembers, ui);.
